????: [cgal-discuss] How to use halfedge data structure of CGAL torepresent a quad (or triangle) mesh?

Hi, There,

I have a 2D quad mesh and want to use halfedge data structure in CGAL to
store it .  But I can't find such an example in CGAL.

Please give me a example or some suggestion to do it, thanks very much.

Here is simple quad mesh:

node
#   x      y
1  0.0   0.0
2  1.0   0.0
3  2.0   0.0
4  0.0   1.0
5  1.0   1.0
6  2.0   1.0
7  0.0   2.0
8  1.0   2.0
9  2.0   2.0

elem
#   n1   n2   n3   n4
1    1     2     5     4
2    2     3     6     5
3    4     5     8     7
4    5     6     9     8


Best

Huayi
